Is there anyway to password protect a dvd from being copied.i have a program called Secukeeper but it only password protects my dvd files on the computer i was trying to have the password burned onto a disc also..is there any way to do it?
Well, I guess you can password protect the DVD from being accessed, but it would not stop the disc from being copied.
Password protection would not work because it has to be part of the DVD Spec. The DVD Spec only allows CSS encryption, so if you encrypt it using another algorithm, it will not play on a DVD Player.
You can try a simple Psuedo ARccOS/RipGuard. You will need to add an unrippable file to the DVD. This would only stop casual copying. An unrippable file does not have to be corrupt. You can burn say 30MB of Garbage Data at the beginning of the Disc and then at some point within this garbage data, put a hole in the DVD with a pin or something.
There are other things to do like burn on really bad media like CMC MAG DVD-R that is about 2 years old, burn garbage data and mark it with a marker to prevent a reader from reading it, etc...
There is an actual way to implement an ARccOS type corruption, but it is very technical and I cannot see how to explain it in under 50 pages.
Ok i ripped the files from a movie to hard drive and have figured out a simple way to make the movie not work with the CloneDVD or DVD Shrink..i wil perfect this if its the last thing i do.
Just make sure that you always do a test burn on DVDRW. Sometimes the copy prevention can seem to work fine on a PC, but it will be a different story when burned.
Also, be careful not to cause too much corruption. You always want to be able to reverse engineer your own corruption just in case it leeks out somehow.
If you want the data to be unaccessible use GPG. Password protection may work with a long enough password but short passwords are easily subject to brute-force attacks and longer ones to dictionary attacks. Cracking passwords is a piece of cake.
GnuPG/GPG/OpenPGP is the way to go. See http://sourceforge.net/projects/winpt. While copy-prevention like the aforementioned methods will prevent the discs from being copied, I would concentrate more effort on making the data inaccessible even if somebody should copy it.
-Do you believe you own your computer and shouldn't be told what you can run and do? Then say *NO* to Microsoft Vista!
-Since half the questions here involve media problems, here ya go: Only use Verbatim or Taiyo-Yuden discs (get your TYs from Rima.com, not Supermediastore or meritline). Forget the rest, no matter what "brand" they sell under. Always burn at 4x speed regardless of the speed rating of this discs or your drive. If you have burn problems with these then you have to update your drive's firmware. For double-layer discs, only use Verbatim DVD+R DL and burn them at 2.4x speed.
